I've updated the Bonus Field mission again (the one unlocked when you complete the prototype) and I've changed the appearance of robots. First it was an army of Mets, then one big Met, then Spark Man, and now it's a random selection of 3 - 6 robots from the new Mega Man 3 and Mega Man 4 updates. A kind of preview of what's to come for those who complete the main game. Most of these robots do not have their official abilities ready yet, so they're all using placeholders right now and will updated when new content is added to the game. Please let me know if you guys have any other ideas for end-game bonus content! :D
